Question

Basal body is associated with the development of
A. Cilia and flagella
B. Cell plate
C. Phragmoplast
D. Kinetochore

Answer 1

Hint: The Basal Body is a structure of protein located at the base of an undulipodium eukaryotic. It is made from a centriole and several additional structures of protein, and is a modified centriole, basically.

Complete Answer:
- A basal body is a protein structure found at the base of an organism. They lie at the base of cilia. Cilia is hair like structure in an oscillatory motion. This structure is connected with motility and is present on the free surface of the cell. These organisms contain nuclei which is enclosed within a nuclear envelope.
- Basal body acts as a nucleus point and which helps in the growth of the microtubules that develop the core of a cilium and flagellum. These centrioles help in development for proteins that in turn further helps in the anchoring of microtubules. These are known as microtubule organising centers (MTOC).
- Within many eukaryotic cells, these microtubules maintain the kind of structure that helps in the movement of vesicles and organelles.
- Basal bodies develop primary cilia and settle at the cell cortex in proximity to plasma membranes during the cycle of a cell. On entry of a cell cycle, cilia breakdown into components and the basal body travels to the nucleus. At the nucleus, the basal body develops centrosomes.
- To evolve mitosis, polarity, cell division, protein trafficking, signalling, motility, and sensation, three of them, that is -Centrioles, basal bodies, and cilia are mandatory.They all play an important role in developing them.

The correct answer is option A, ‘Cilia and flagella’.

Note: Basal bodies have several organisms in the kingdoms of animals and protists.
Algae, like Chlamydomonas, have basal bodies in general, whereas no, taller plants and fungi do not have basal bodies.
